I thought, judging from the response, Richard was on his ignore list.Keep in mind, he is very protective of Richard for some reason.
I and at least one other poster have been trying to explain to you where you've gone wrong with your test.
I was too. Or at least that's what he said, which shows the credibility level of his words.was on his ignore list.
For a bit of fun, if you are ever in Nova Scotia, take Route 2 from the Trans Canada toward Great Village, Economy and Parrsboro. A ways past Parrsboro on the way to Advocate, in Port Greville I think, you will see a misplaced lighthouse (no water to be seen except a little brook). Pull in there, there is an Age of Sail Museum with lots of old tools. Not much in the way of big machine tools, but they say they have the world's largest collection of wood planes, and I believe them. They used to launch some pretty big ships in that tiny brook when the tide was in.
Only 2 pages on 12 of yours.
But once you consider what kind of business he is in, it's no longer strange.
Who do you mean "we", you and your business associate?
It is to those who sell things. It's thicker the better for them.
We are members of the same secret society that rules the world.Keep in mind, he is very protective of Richard for some reason.
It was a very painful moment to re-read your posts, not one that does not attack one member or another. None bringing any information, idea, experience, or anything positive and interesting.
The 0 level is always matched in your posts, and , indeed, lot of members are blind of them.
You are now back in my ignore list: You will not find many people to answer you.

For instance, there are all sorts of trade-offs and compromises in, for instance, thru - hole copper plating of circuit boards, mostly due to the non-uniformity of trying to coat the sides of the thru-holes to the same thickness as the lands, due primarily to the unequal distribution of current around defects and features with high aspect ratio. In cross section one gets a dumbbell or dog-bone effect, which is highly undesirable and a stress point, due to changing microstructure.
Different solution chemistries exhibit different "throwing power" which is the ratio between the thinnest and thickest point in the coating. In copper and nickel plating, you can improve throwing power by decreasing the metal concentration in the bath up to a point... maybe 1:2 before other problems crop up
What is usually done in contemporary installations is using proprietary systems that rely on organic levelers and brighteners, which selectively adsorb on high current density (& higher voltage to drive it) peaks and asperities, and get rapidly depleted in low current density areas allowing preferential plating there. This forces a redirection of the primary field by manipulating the diffusion layer to advantage. As they are added at low levels, maintaining the system integrity is challenging in many installations.
Back to this analogy thought process, since current accounts for the quantity of metal deposited ( 1 Faraday = 1 mole of electrons, 6.023* 10^23) , whereas voltage accounts for the type of deposit and its quality descriptors, you want to control the current (current density as much as possible locally) precisely, as that determines how much deposit is laid down. Conversely, in anodizing, it's the voltage - time multi factor variable that controls the quality and quantity of anodic film... current plays a secondary role of supporting the voltage needed per unit area. Lots of variables in both systems to manipulate, and also depends on the preferences of the end user.
I've got some other thoughts on this but my brain hurts 'cause I'm too old... and this post is getting into TLDR territory

Never had that problem with my former work
Far and away for sure, spend it or give it to Uncle Sam ... but then I'm retired and have a big recorded library
I do too... one of them is my spouse's great grandfathers' hammer... which, after 2 heads and three handles, is still "taking a licking & keeping on ticking"

^It's interesting seeing the analogs to my work, which is electrochemical sensors (the academic world likes to call them something else, but when you get to the muckety-muck, it's electrochemical), and how empirical much of this effort really is. And intuitive. Sadly there's not quite as neat of self-exhausting reactions for electroplating as there are for gas phase processes like ALE and ALD (atomic layer Etching and Depositing, respectively) to truly grow even films over complex geometries.
My tool cost far outpaces my material cost, but I also have a lifetime ahead of me to flip that and may never, given most of my tools are for hobby. More so, I hope to recoup in terms of project cost as I embark into home remodeling work/etc. Building the occasional speaker is a bonus.

None of what you quoted show what you claimed I said ("all audio pros are snake oil sellers.
...
manufacturers of audio equipment think only of selling fake equipments by telling lies. Everybody knows that.")
Try again.
Whilst the total value of my system is roughtly the same as my annual music spend, how does that work if you have a subscription to a streaming service? The top Qobuz subscription is $300 a year...
Since I restarted I don't think I'm over $1000 yet and have given 100X that to local and other charities in the same time frame. $6000 buys a complete house kit for a family of 4 in South America built by other volunteers.
Though my phono pre is built by me from hand matched unobtainium FET's and must be at least valued at $15,000.

I cut my teeth on Jones & Shipman, popular down here, nice grinders. Grinding die blocks / buildup on Blohm HFS12 you have to be pretty careful.
There were holes in the wall / roof where people got a little enthusiastic about cut depth = instant projectile off the magnetic table.
Large surface grinders need a healthy dose of respect.

yep, they are at my disposal if i have a project I want to work on. Like those custom, one-off amps of Damir's for myself. They did drawings for chassis, got them milled and machined. Did pcb and ordered all parts, did assembly and testing. Silk screen. Everything for me. Doesnt mean I, personally, am selling anything.
I am retired. Life is good.

Yes your signature and the unobtanium FETs would actually jack up the retail value (especially given it is literally one of a kind).
Many of us get into this DIY hobby partly out of dissatisfaction with commercially available products, and partly because we think we will save a bit of money. Then we buy tools (they don't count toward cost of the electronics we build), circuit boards, parts... but if you need 3 10K resistors for this project you might as well buy 10, lower unit cost, surely I'll use them next time, etc. Then an enclosure z and a better power supply, and... I built two phono preamps in the last few years. In theory each of them could be built for $100 or less; in reality each cost me well in excess of $200 in parts, never mind my time, and I wouldn't sell either of them for less than $400 (which is probably closer to real cost), but I wouldn't sell them at all anyway. I love the fact that they both are amazingly good (I take no credit for that) but have completely opposite designs. One is MM and uses opamps and is great; the other is MC and uses unobtanium FETs and is great. Sadly I can't afford two phono rigs and my tonearm doesn't have removable headshell, so switching is a very big deal. Maybe at some point I will be able to get a second record player.
So Scott I won't be bidding on your SW signature phono preamp, but I still want to build one someday. Props for the charitable contributions, that is also an area where I will be stepping up my game next year but not to that level (my new employer encourages giving back and will match some contributions). However, I have been dropping a few coins on vinyl in the last few years, so at least even vs electronics purchases (not counting tools).
PS: If I ever do bid on a SW Signature Phono Preamp, I better see a partly melted capacitor or I'll know it's a fake!
